At first I just wanted to say how much I love Pilgrimage and all of it's variations. Thank you Rydygier for creating this mission, it's the only thing I'm playing on Arma 3 for few yers now! I've been stalking this forum for a long time but this is my first post here 🙂
The Silent-Unseen version is a very good and refreshing thing for Pilgrimage, especially that I'm from Poland too (Pozdrowienia z Torunia! 🙂 ).
But I think that there is a game-breaking bug: After a while the game stops spawning civilians, loot and ambient combat enemies. It also doesn't save near the churches. I played three times and I always had this problem.
I have loot, civilians and intel in first village I visit, but after some time the other places are entirely empty (exept the enemies that spawned at the start of the mission). Every time I tried different settings for civilians and loot, and I have the 3D icons set to show all.
